So I have went through the process of renewing my Standard UCC SSL Certificate on my Exchange 2013 server including submitting the CSR to GoDaddy, downloading the finished cert, installing the intermediate certs (again) but it falls apart when I click "Complete". I input the UNC path to the cert, click ok, the window processes for a moment then takes me right back to the "Certificates" page in 2013 and that's IF it doesn't give me this error message: A special Rpc error occurs on server EXCH2013HYBRID: Cannot import certificate. A certificate with the thumbprint 155D2A21D13363B7BB0EC03E2B236CB913E6163F already exists.A special Rpc error occurs on server EXCH2013HYBRID: Cannot import certificate. A certificate with the thumbprint 155D2A21D13363B7BB0EC03E2B236CB913E6163F already exists.. The new and old certs are in the "Certificates" snap-in under "Personal" however the new cert doesn't have the message "You have a private key that corresponds to this certificate". When I check the event log I see eventID 6 in the MSExchange Management log which states Cmdlet failed. Cmdlet Import-ExchangeCertificate, paramenters -PRivateKeyExportable "True" -FileName "\\server\\folder\mynewcert.crt" -Server "myserversname.com". Can anyone tell me what I am doing wrong or missing please??
The server exists in a hybrid format with Office 365 running on Version 15.0 (Build 1044.25) on Windows Server 2012 R2 Standard which is fully updated.
